The company cited "differences in personality that began with different opinions on music" as the main reason for Hyunseung's exit.
"Jang Hyunseung and the five members have been talking and consulting continually with the company about making a change to team activities due to differences in personality that began with different opinions on music. After long deliberation between all the members, it was agreed that the group would part company with Jang Hyunseung and the team would be reorganized," the statement continued.
Cube also confirmed that the rest of BEAST are currently preparing for a comeback and will continue promoting both in South Korea and abroad.
"BEAST has been working hard for the past seven years without rest for the fans and their shared goal of reaching the top. Because of this, this decision was not easy for the members, company, or anyone. BEAST, which has now changed to a five-member group, plans to get ready to release a new album in 2016 and be active both domestically and overseas. Please continue to support and show interest in both BEAST and Jang Hyunseung, who will be doing their best in their own positions. Thank you," the statement concluded.
This shocking news comes just weeks after Hyunseung made headlines for his "unprofessional" behavior and recent "attitude problem."
The singer has reportedly missed several of BEAST's activities, including concerts and fan meetings, for personal reasons, which angered fans of the veteran male group.

Obviously he was unhappy where he was at, so I wish him and the other five members much success and happiness whatever direction they take now. I'm confident that even though it may be different, Beast will continue to be great, because with all that talent how could it be otherwise?
